Description
Paraformaldehyde (PFA) is a multi-use solution. It is commonly used for research purposes, but may also be used to fix nervous and cardiovascular tissues after it has been depolymerized in a formaldehyde-based solution. It contains a neutral pH level between 6.8 and 7.2, ensuring that tissue applications retain their protoplasmic structures and details for microscopic examination. Our paraformaldehyde is unique in that it contains two aldehydes per molecule thus providing a stronger fixation.
